Letters Patent or" the United States No. 1,129,882,

granted March 2, Roland F. McFeely.

In supplying mechanism of the type referred to above, as heretofore constructed, a separator is 1915 on an application of provided arranged to move transversely of the ends of a plurality of raceways from which fasrated iastenings at times coinciding substansicily with the delivery of the fastenings by the separator. Means is 'provided for imparting a plurality of reciprocating movements to the separator to separate a plurality ci sets of fastenings, and the receiving member is arranged to hold a set of separated fastenings in transit until another set is separated and then to deliver to the fastening-inserting means at substantially the same time fastenings separated at dierent times. The separator is provided With oblique slots terminating in enlargements or eyes and as the separator moves across the ends of the raceways the fastenings move along the slots and are delivered through the eyes to the receiving member.

separation to the points of delivery, so thatv sometimes one or more of the asteningsmay be delivered by the separator before the receiving member is moved into position to receive the fastenings. As a result, more than one fastening may be delivered into the same hole in the receiving member by the separator, This may cause the receiving member to jam, particularly if the head of one of the fastenings extends into one of the openings in the cap plate, so that there is a considerable loss of time by the operator in removing the misplaced fastening.

f It is an object of the present invention to provide a fastening supplying mechanism of the type referred to aboveso organized that the above-mentioned dinict-.lty will be obviated. As illustrated, the receiving member is provided as heretofore with a plur y ci sets of fastening receiving holesvfor rec -ving the separated fastenings, and according to afeatnre of the invention novel means is provided, operating in timed relation to the movements of the separator, for moving the receiving memberA into position to receiveeach set oi separated fastenings before the fastenings are delivered by separator'.v As shown herein this means includes a rock shaft for operating the receiving member and novel mechanism for operatively connecting the rock shaft to, and disconnecting the rock shaft from, the usual crank shaft for operating the separator in each movement of the crank shaft to reciprocate the separator, so as to operate the receiving member in the desired time'relation to the movements of the separator: It is' a characteristic also of the construction shown that the receiving member is `moved into position to deliver the irst set-of separated fastenings before the second set of fastenings are delivered by the separator.

With the above and other objects and features in view the inventionwill now be described with reference to the accompanying drawings and will be pointed out in the claims.

The fastening supplying mechanism herein ilioo lustrated is of the same general type-as that 1.10

disclosed in the above-mentioned Letters Patent. Such mechanism comprises a raceway block 18 provided with va group of tack delivering raceways 12 to which tacks are supplied from a hopper (not shown) which is oscillated to lift tacks and supply them to the raceways. A separator slide 14 is mounted for reciprocation transversely of the raceways 12 in a bracket 16 which is usually secured to the head of the ymachine and which is arranged also to support the hopper. Secured to the separator slide 14 is aseparator plate 18 provided with separating points 26 and oblique slots 22 terminating in enlargements orl eyes 24 to permit the heads of the tacks to drop, aiter separation, through openings 25 in member 26 and into tack receiving holes formed in a receiving member 28 mounted for endwise movement between the member 26 and a conductor or tack tube anchor plate 30.

In the illustrated construction the raceway block 10 is provided with eleven raceways and the separating mechanism is arranged to be reciprocated twice in each cycle of operation of the machine in which the mechanism is incorporated to separate and deliver twenty-two tacks.

As more fully explained in the above-mentioned McFeely patent the hopper from `which the tacks are supplied to the raceways 12 is oscillated once for each cycle of operations of the machine, and connected to the hopper operatingrshaft by means of a universal joint (not shown) is an inclined shaft 40 having a gear 42 secured to its lower end meshing with a pinion 44 formed upon a crank shaft 46, Fig. 8. The crank shaft 46 is provided with a crank 48 connected to a block 50 in a fork depending from the median portion of the separator slide 14 and from which that slide and the separator plate 18 receive a complete reciprocation from the oscillatory movement of the gear 42 and the hopper in one direction and a second complete reciprocation from the oscillatory movement of the gear 42 and the hopper in the other direction. Thus two sets of fastenings are separated and delivered by the separator 18.

To receive the separated fastenings the receiving member 28 is provided with two sets of fastening receiving holes 36, 38 alternately arranged and in order to insure that each set of separated fastenings will be delivered into the proper holes means is provided which will now be described operating in timed relation to the movements of the separator for moving the receiving member into position to receive each set of separated fastenings before the fastenings are delivered by the separator. YAs illustrated this means comprises an operating shaft 52 to one end of which is secured a gear 54 the teeth of which mesh with the teeth of the pinion 44. The gear 54 is provided with a greater number of teeth than the gear 42 so that the angle of oscillation of the shaft 52 is less than that of the shaft 40.

Mounted above the shaft 52 iny parallel relation` thereto isa rock shaft 56 provided with an upwardly extending arm 58 arranged yieldingly to operate the receiving member 28 by means of spring plungers 62 as clearly shown in Fig. 2. The plungers 62 are mounted in the brackets 16 and are provided with reduced portions 64 passin'g through rbushings 66 and having nuts 68 threaded upon their outer ends for adjusting the endwise positions of the plungers 62 in the brackets 16. The `bushings 66 are provided with collars 70 seated in slots formed in the opposite end portions of the receiving member 28 and surrounding the reduced portions 64 of the rod 62 between the bushings 66 and shoulders formed upon the rods 62 are springs '78.

The shaft 56 is provided with a downwardly extending arm 7 2 diameirically opposed to the arm 58 and having a tooth-shaped end arranged to enter a single notch 74 formed in a disk i6 secured to the shaft 52, the shaft 56 accordingly being oscillated by the movement of the disk 76. The notch 74 is moved equal distances on opposite sides of the center ci oscillation of the shaft 52 and its movement in each direction continues after the disk 76 has ceased to swing the arm '72, as will be evident by reference to Figs. 3 and 4. That is, the angle of oscillation of the disk 76 is greater than the angle of oscillation of the shaft 56 which carries the arms 58 and 72 during each rotation of the pinion 44 to impart a complete reciprocation tothe separator 18. It Will, therefore, be readily seen that the movements of the receiving member 28 into position to receive each set of separated astenings will be completed before the fastenings are delivered by the separator 18. More particularly, as shown in Figs. 1, 3 and 8, the parts are in the positions which they assuine when the machine is at rest. As the pinion 44 is rotated during the oscillatory movement of the gear 42 in one direction to impart a complete reciprocation to the separator 18 the notch '74 is moved from the position shown in Fig. 3 to the position shown in Fig. 4. The shaft 56 is urged in a clockwise direction as viewed in Fig. 2 by a spring pressed plunger 78, Fig. 1, engaging the arm 58 so that as the notch 74 approaches the center of oscillation of the shaft 52 the arm "i2 will enter the notch '74 and as the shaft 52 continues to move in a counterclockwise direction the shaft 56 will be rocked in a clockwise direction during the intermediate portion of a turning movement of the shaft 52 from the position shown in Fig. 3 to the position shown in Fig. 4. Clockwise movement or the shaft 56 moves the receiving member 28 through the arm 58 and spring plunger 62 to the right until the fastening receiving holes 36 are in position to receive a set of separated fastenings from the openings 25, Fig. 6. At this time the arm 72 passes out of the notch 'Matter which the shaft 52 continues to rotate in a counterclockwise direction until the separator 18 delivers a set of fastenings into the holes 36. During the oscillatory movement of the gear 42 in the opposite direction to impart a second complete reciprocation to the separator 18 through the pinion 44 and crank 48 the shaft 52 is rotated in a clockwise direction, Fig. 2, and through the action of the arm 72 and the notch 74 the shaft 56 is rocked in a counterclockwise direction moving the receiving member 28 to the left to bring the first set of holes 86 into discharging position and the second set of holes 38 into position to receive a second set of fastenings before the fastenings are delivered by the separator 18. The arm 72 is moved into the notch 74 in the clockwise movement of the shaft 56 by a spring pressed plunger 80, Fig. 1.

1t will be further noted by reference to Fig. 2 that as the arm 58 is swung into substantially a central position no movement is imparted to the receiving member 28, there being merely an expansion of one or the other of the previously compressed springs 73. As this occurs the separator 18 makes its rearward stroke. As the arm 58 passes a central position it begins to move the receiving member 28 through one or the ether-of theVY plungers S12-and springs 73 toward its fastening receiving position asthe separator 18 is beginningits fastening separating stroke, this movement of 'the receiving member 28 being completed as hereinbefore described before the separator has been moved into position to deliver a set of fastenings.
